Исследование состава аналитов на наличие мономеров и прочих соединений после инкубации матриксов в буфере проводили ежемесячно с помощью жидкостной хроматографии. Кардиотоксичность аналитов оценивали на модели изолированного сердца крыс-самцов линии Wistar методом Langendorff. На фоне введения аналитов измеряли скорость коронарного протока и изучали ферментативную активность миокардиальной фракции креатинфосфокиназы и лактатдегидрогиназы. Полигидроксибутират/валерат и поликапролактон не имели достоверных признаков распада до мономеров через 6 месяцев гидролитической деградации, а фосфатно-солевой буфер, в котором инкубировали данные образцы в течение 6 месяцев, не вызывал кардиотоксического эффекта в экспериментах на модели изолированного сердца и достоверного повышения активности ферментов в перфузате.</p></abstract><trans-abstract xml:lang="en"><p>The evaluation of cardiotoxicity of the degradation products of electrospunpolyhydroxybutyrate-valerate and polycaprolactone tubular matrices, subjected to 6-month hydrolytic degradation in sterile phosphate buffered saline (PBS) at 37 ºC, was performed. After matrices incubation in PBS, high performance liquid chromatography was used to analyze individual analytes for the presence of monomers and other compounds each month. Cardiotoxicity of analytes was evaluated in a model of isolated perfused rat heart (male Wistar rats) using the Langendorff technique. The rate of coronary flow and enzymatic activity of creatine phosphokinase and lactate dehydrogenase myocardial fractions were measured during the analytes injections. Both, polyhydroxybutyrate-valerate and polycaprolactone, had no significant signs of hydrolytic degradation of polymers into monomers after 6-month storage time. PBS after 6-month incubation of the studied samples did not produce any cardiotoxic effect in the experiments on isolated rat heart and did not demonstrate any significant increase of enzyme activity in the perfusate.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>биорезорбируемые полимеры</kwd><kwd>гидролитическая деградация</kwd><kwd>лактатдегидрогеназа</kwd></kwd-group><kwd-group xml:lang="en"><kwd>bioresorbable polymers</kwd><kwd>hydrolytic degradation</kwd><kwd>chromatography</kwd><kwd>cardiotoxicity</kwd><kwd>creatine phosphokinase</kwd><kwd>lactate dehydrogenase</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Российский научный фонд, Федеральное государственное бюджетное научное учреждение «Научно-исследовательский институт комплексных проблем сердечно-сосудистых заболеваний»</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Алехин А.
